Delhi Dome of Faith provides a niche and diminishing return landmark function. Especially when compared Tower of Victory assuming standard optimal delhi play style.
Why is it niche?
DOF is niche because scholars are niche. You only need so many scholars early and given delhi play style requires obtaining and defending sacred sites, the gold saving of DOF become a non-factor later on when the game gets going. Next the added research speed obtained are minute early on and a detriment to your ability to product units and/or build your blacksmith(s).
For example Making 3 DOF scholars at feudal age up ( having 4 total) vs making 1 scholar in transition to feudal (having 2 total) will result in the DOF route saving you 7 seconds in standard econ upgrades but costing you an additional 110g ? 110 resources is almost the cost of a blacksmith and is absolutely NOT paid for in having upgrades 7-10s earlier.
The only examples proven by high levels of evenly matched play where DOF landmark contends with the benefits of Tower of Victory, is when you’re allowed to engage in small skirmishes and the high health pool of the scholar can help soak incoming damage; or when high activity high high raiding takes a toll and the raiders can return to satellite healing centers. However in the mid to long run; the TOV pulls out clearly as THE better landmark option.
These are ideas to correct the Dome of Faith deficiencies:
Introduce the imam area of effect healing ability thru a special 350g upgrade ONLY in the Dome of Faith!! In combat healing is rare among the factions but in my opinion the concept well suits the Delhi as THE faction centered around scholarship and elephant** (kekw). The Imam like aoe healing is extremely functional and it scales with army size; so there is no diminishing returns and it will actually scale the more premium units you have, since premium units useually have high HP and/or armor.
2nd idea is boring…but it would result in the momentum builder originally desired by the devs. The idea is once the DOF landmark completes it should instantly spawn 3-4 scholars (4-5 total if it’s the first mosque built). Then it should do so again once you hit castle (3-4 more scholars spawn at the DOF). And finally do so again in Imperial age.
This is a less eventful buff… but functional and practical given the playstyle alternative it can offer. Say you want to 2TC play (it’s not optimal but given certian matchups like versus China its viable) having 4-5 total scholars essentially for free will offer you 60-80% research speeds on all your upgrades. Alternatively going TOV and making 1 scholar in transition? Before going into the 2nd TC play would cost you 130g (significant delay on 2ND TC) and garner you only 27% increase in research speeds. That’s a comparative 33-53% faster research time and 130 reso##### to spend elsewhere (faster 2nd TC and or BSM). To put it in seconds thats 24 to 36 seconds FASTER standard economic upgrades!!! 24 to 36s is MEANINGFUL. Secondly, the immediate value of 3-4 free scholars (4 to 5 total) also provides a defensive posture against early aggression since that many scholars can sustain against small raids.
However even these savings have diminishing returns in the long run where feudal upgrades have long been researched. This is why i believe this landmark needs to keep on giving thru every age up. Providing the additional 3 or so scholars each age up will legitimize the FREE RESEARCH advantage of Delhi. Currently the technologies are NOT practically free beyond feudal because they would take too long with 0-1 scholar research speed bonus. While sacred site gold goes hand-and-hand with scholar product, this is the case because delhi has no alternative use for direct gold use until castle age.
